The Challenge: Coordinating holidays, managing wishlists, and organizing "Secret Santa" games often leads to duplicated gifts and chaotic chats. Wizzly was built to solve this by unifying event organization and gift registries into one seamless platform. It needed to work both as a standalone Web App and a Telegram Mini App (TMA).

My Solution: I developed the complete system architecture, focusing on high performance, complex social mechanics, and a flawless user experience.

Next-Gen Frontend: Built with Next.js 15 and React 19 using Server Components. Implemented Zustand for state management and Framer Motion for dynamic UI animations (like the Secret Santa draw).

Robust Backend (Go): Developed a high-performance REST API using Go and GORM. Designed a strict relational PostgreSQL database to handle social graphs, event invites, and anonymous gift reservations.

Complex Algorithms: Engineered an intelligent matchmaking algorithm for the "Secret Santa" feature that guarantees no crossed paths or self-assignments.

Smart Integrations & i18n: Implemented seamless authorization (Telegram, Google, Apple) with smart account merging. Integrated a Telegram bot for push notifications. The platform was also fully localized into 3 languages: English, Russian, and Armenian.

Social Mechanics: Built a social graph to track friendships, online statuses, and automatic birthday countdowns.

The Outcome: A deeply functional, production-ready SaaS platform that eliminates the stress of event planning through smart automation and gamification.
